74LCX16543
Low Voltage 16-Bit Registered Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The LCX16543 contains sixteen non-inverting transceivers
containing two sets of D-type registers for temporary stor-
age of data flowing in either direction. Each byte has sepa-
rate control inputs which can be shorted together for full
16-bit operation. Separate Latch Enable and Output
Enable inputs are provided for each register to permit inde-
pendent input and output control in either direction of data
flow.
The LCX16543 is designed for low voltage (2.5V or 3.3V)
VCC applications with capability of interfacing to a 5V signal
environment.
The LCX16543 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 5.2 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s
±24 mA Output Drive (V
CC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human Body Model
> 2000V
Machine Model
> 200V
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
